This plant grows on the hills around Tula, TAMPS, this location being a
hill to the north west, which is the location for the town’s rubbish dump
and where severe soil erosion and quarrying occurs, all posing threats to
these plants. Local children are also said to eat the plants as sweets.
The plants are very small and difficult to find out of flower.
Thelocactus tulensis and Stenocactus sp. are also found here.
